1、首先申请一个服务器和邮箱域名，并设置好域名解析，这里我以192.168.1.12 test.com为例：登录域名服务提供商后台，设置域名解析：记录类型 主机记录 记录值 MX优先级A @ 192.168.1.12 --A www 192.168.1.12 --A mail 192.168.1.12 --MX @ mail.test.com 5配置完毕后验证配置是否生效：$ ping mail.test.com如果能提示出你的服务器的IP地址， 证明 mail和www的配置已经生效。$nslookup -qt=mx mail.test.com能显示你的域名mail.test.com，就代表你的 MX记录配置正确。
2、第二，服务器准备工作，关闭Selinux和防火墙,删除默认的sendmail服务$setenforce 0$ servicefirewalld stop$yum remove sendmail
3、第三，安装mysql$ yum install mysql$servicemysqldrestart
4、第四，安装postfix、添加用户组、修改主配置文件$ groupadd -g 2525 postfix$ useradd -g postfix -u 2525 -s /sbin/nologin -M postfix$ groupadd -g 2526 postdrop$ useradd -g postdrop -u 2526 -s /sbin/nologin -M postdrop$chown -R postfix:postdrop /var/spool/postfix$ chown -R postfix:postdrop /var/lib/postfix/$ chown root /var/spool/postfix$ chown -R root /var/spool/postfix/pid$ yum install postfix安装完毕后修改配置文件：第一个是 ：postfix 的配置文件 /etc/postifx/main.cf ， 需要修改的内容如下所示，其他的用默认即可。command_directory = /usr/sbinconfig_directory = /etc/postfixdaemon_directory = /usr/libexec/postfixdata_directory = /var/lib/postfixdebug_peer_level = 2debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin ddd $daemon_directory/$process_name $process_id & sleep 5html_directory = noinet_protocols = ipv4mail_owner = postfixmailq_path = /usr/bin/mailqmanpage_directory = /usr/local/mannewaliases_path = /usr/bin/newaliasesqueue_directory = /var/spool/postfixreadme_directory = /usr/share/doc/postfix-2.10.1/README_FILESsample_directory = /etc/postfixsendmail_path = /usr/sbin/sendmailsetgid_group = postdropunknown_local_recipient_reject_code = 550#Base addinginet_interfaces=allmyhostname=mail.test.commydomain=test.commyorigin=$mydomain#配置虚拟用户时需要将此项注释#mydestination=$mydomain,$myhostname home_mailbox=/var/mailboxalias_maps = hash:/etc/aliases################################基于smtp auth的配置选项##############smtpd_sasl_auth_enable = yessmtpd_sasl_security_options = noanonymousmyNetworks = 0.0.0.0/0smtpd_sasl_local_domain=$mydomainsmtpd_recipient_restrictions =permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination#############################adding virtual基于虚拟用户的配置选项##########virtual_mailbox_base=/var/mailboxvirtual_alias_maps=mysql:/etc/postfix/mysql_virtual_alias_maps.cfvirtual_mailbox_maps=mysql:/etc/postfix/mysql_virtual_mailbox_maps.cfvirtual_mailbox_domains=mysql:/etc/postfix/mysql_virtual_domains_maps.cfvirtual_uid_maps=static:2525virtual_gid_maps=static:2525virtual_transport = virtual
5、第五，安装dovecot，修改配置文件$yum install -ydovecot dovecot-mysqldovecot的配置文件 /etc/dovecot/dovecot.conf，需要修改的内容如下所示，其他的默认即可。[root@mail ~]# cd /etc/dovecot/[root@mail dovecot]# vim dovecot.conf protocols = imap pop3 lmtplisten = *, ::base_dir = /var/run/dovecot/!include conf.d/*.conf[root@mail dovecot]# cd conf.d/[root@mail conf.d]# vim 10-auth.confdisable_plaintext_auth = no[root@mail conf.d]# vim 10-mail.confmail_location = maildir:~/Maildirmail_location = maildir:/var/mailbox/%d/%n/Maildirmail_privileged_group = mail[root@mail conf.d]# vim 10-ssl.confssl = no[root@mail conf.d]# vim 10-logging.confinfo_log_path = /var/log/dovecot.infolog_timestamp = "%Y-%m-%d %H:%M:%S "[root@mail conf.d]# cp auth-sql.conf.ext auth-sql.conf[root@mail conf.d]# vim auth-sql.confpassdb {driver = sql# Path for SQL configuration file, see example-config/dovecot-sql.conf.extargs = /etc/dovecot/dovecot-sql.conf.ext}userdb {driver = sqlargs = /etc/dovecot/dovecot-sql.conf.ext}编辑dovecot通过mysql认证的配置文件：[root@mail conf.d]# vim /etc/dovecot/dovecot-sql.conf.extdriver = mysqlconnect = host=localhost dbname=extmail user=extmail password=extmaildefault_pass_scheme = CRYPTpassword_query = SELECT username AS user,password AS password FROM mailbox WHERE username = '%u'user_query = SELECT maildir, uidnumber AS uid, gidnumber AS gid FROM mailbox WHERE username = '%u'
6、第六、安装courier-authlib下载解压并并编译[root@mail ~]# wgethttps://sourceforge.net/projects ... hlib-0.66.2.tar.bz2[root@mail ~]# tar xf courier-authlib-0.66.2.tar.bz2[root@mail ~]# cd courier-authlib-0.66.2[root@mail ~]# ./configure \--prefix=/usr/local/courier-authlib \ --sysconfdir=/etc \ --without-authpam \ --without-authshadow \ --without-authvchkpw \ --without-authpgsql \ --with-authmysql \ --with-mysql-libs=/usr/lib64/mysql \ --with-mysql-includes=/usr/include/mysql \ --with-redhat \ --with-authmysqlrc=/etc/authmysqlrc \ --with-authdaemonrc=/etc/authdaemonrc \ --with-mailuser=postfix这里会报错，configure: error: The Courier Unicode Library 1.2 appears not to be installed.提示Courier Unicode Library没有安装，我们下载courier-unicode-1.2并编译安装。[root@mail ~]# wgethttps://sourceforge.net/projects/courier/files/courier-unicode/1.2/courier-unicode-1.2.tar.bz2[root@mail ~]# tar xf courier-unicode-1.2.tar.bz2[root@mail ~]# cd courier-unicode-1.2[root@mail courier-unicode-1.2]# ./configure[root@mail courier-unicode-1.2]# make && make install再次编译courier-authlib就没问题了，别忘了make && makeinstall2、配置courier-authlib[[email protected]]# chmod 755 /usr/local/courier-authlib/var/spool/authdaemon[[email protected]]# cp /etc/authdaemonrc.dist/etc/authdaemonrc[[email protected]]# cp /etc/authmysqlrc.dist/etc/authmysqlrc[[email protected]]# vim /etc/authdaemonrcauthmodulelist="authmysql"authmodulelistorig="authmysql"[[email protected]]# vim /etc/authmysqlrcMYSQL_SERVER localhostMYSQL_USERNAME extmailMYSQL_PASSWORD extmailMYSQL_SOCKET /var/lib/mysql/mysql.sockMYSQL_PORT 3306MYSQL_DATABASE extmailMYSQL_USER_TABLE mailboxMYSQL_CRYPT_PWFIELD passwordDEFAULT_DOMAIN test.comMYSQL_UID_FIELD '2525'MYSQL_GID_FIELD '2525'MYSQL_LOGIN_FIELD usernameMYSQL_HOME_FIELD concat('/var/mailbox/',homedir)MYSQL_NAME_FIELD nameMYSQL_MAILDIR_FIELD concat('/var/mailbox/',maildir3、courier-authlib添加服务启动脚本及其他[[email protected]]# cp courier-authlib.sysvinit /etc/init.d/courier-authlib[[email protected]]# chmod +x /etc/init.d/courier-authlib[[email protected]]# chkconfig --add courier-authlib[[email protected]]# chkconfig courier-authlib on[[email protected]]# echo "/usr/local/courier-authlib/lib/courier-authlib" >> /etc/ld.so.conf.d/courier-authlib.conf[[email protected]]# ldconfig[[email protected]]# service courier-authlib startStarting Courier authentication services: authdaemond4、smtp以及虚拟用户相关的设置[root@mail ~]# vim /usr/lib64/sasl2/smtpd.conf //文件不存在，要自己创建pwcheck_method: authdaemondlog_level: 3mech_list: PLAIN LOGINauthdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket
7、第七、安装extmailextmail和extman可通过这两个链接下载http://7xivyw.com1.z0.glb.clouddn.com/extmail-1.2.tar.gzhttp://7xivyw.com1.z0.glb.clouddn.com/extman-1.1.tar.gz1、创建目录并解压[root@mail ~]# mkdir -p /var/www/extsuite[root@mail ~]# tar xf extmail-1.2.tar.gz -C /var/www/extsuite/[root@mail ~]# mv /var/www/extsuite/extmail-1.2/ /var/www/extsuite/extmai2、更改extmail的配置文件[root@mail ~]# cd /var/www/extsuite/extmail[root@mail extmail]# cp webmail.cf.default webmail.cf[root@mail extmail]# vim webmail.cfSYS_SESS_DIR = /tmp/extmailSYS_UPLOAD_TMPDIR = /tmp/extmail/uploadSYS_USER_LANG = zh_CNSYS_MIN_PASS_LEN = 8SYS_MAILDIR_BASE = /var/mailboxSYS_MYSQL_USER = extmailSYS_MYSQL_PASS = extmailSYS_MYSQL_DB = extmailSYS_MYSQL_HOST = localhostSYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sockSYS_MYSQL_TABLE = mailboxSYS_MYSQL_ATTR_USERNAME = usernameSYS_MYSQL_ATTR_DOMAIN = domainSYS_MYSQL_ATTR_PASSWD = passwordSYS_AUTHLIB_SOCKET = /usr/local/courier-authlib/var/spool/authdaemon/socke3、建立临时文件目录与session目[root@mail extmail]# mkdir -p /tmp/extmail/upload[root@mail extmail]# chown -R postfix.postfix /tmp/extmail/
8、第八、安装extman1、解压extman[root@mail~]# tar xf extman-1.1.tar.gz -C /var/www/extsuite/[root@mail~]# cd /var/www/extsuite/[root@mailextsuite]# mv extman-1.1/ extman2、更改extman配置文[root@mailextsuite]# cd extman/[root@mailextman]# cp webman.cf.default webman.cf3、更改cgi目录属主属组[root@mailextman]# chown -R postfix.postfix /var/www/extsuite/extman/cgi/[root@mailextman]# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/4、导入数据库由于数据库不能识别TYPE=MyISAM，所以这里直接导入会出错，先编辑extmail.sql数据库文件，将TYPE=MyISAM更改为ENGINE=MyISAM[root@mailextman]# vim docs/extmail.sql:% s/TYPE/ENGINE/g共有五处修改导入还是会报错[root@mailextman]# mysql -uroot < docs/extmail.sqlERROR 1364 (HY000) at line 31: Field 'ssl_cipher' doesn't have a default value此处需要修改my.cnf配置文件[root@mailextman]# vim /etc/my.cnf# Recommended in standard MySQL setup#sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES //将这行注视掉，重启mysql，这里需要注意的是，等数据库导入成功后，这项是不可以去掉注释的，不然mysql就启动不起来了。再次导入数据库[root@mailextman]# mysql -uroot < docs/extmail.sql [iyunv@localhost extman]# mysql -uroot < docs/init.sql5、创建数据库用户extmail并授予权限mysql> GRANT ALL ON extmail.* to extmail@'%' identified by 'extmail'; Query OK, 0 rows affected (0.00 sec)mysql> FLUSH PRIVILEGES;Query OK, 0 rows affected (0.00 sec)6、复制四-4提到的配置文件[root@mail~]# cd /var/www/extsuite/extman/docs/[root@maildocs]# cp mysql_virtual_* /etc/postfix/6、为extman创建临时目录[root@mailextman]# mkdir /tmp/extman[root@mailextman]# chown -R postfix.postfix /tmp/extman/
9、第九、启动postfix、dovecot、saslauthd$ service postfix restart$ service dovecot restart$ service saslauthd restart[root@mail extman]# ss -tnluo | grep :25tcp LISTEN 0 100 *:25 *:* [root@mail extman]# ps aux | grep dovecotroot 22200.10.3156161508 ?

10、第十、测试虚拟用户[root@mail courier-authlib-0.66.2]# /usr/local/courier-authlib/sbin/authtest -s [email protected] succeeded. //显示这个表示成功，测试时使用的是[email protected]，因为我们导入的数据库init.sql里面自带了这个。Authenticated:[email protected](uid 2525, gid 2525)Home Directory: /var/mailbox/extmail.org/postmaster//这里需要注意/var/mailbox这个目录现在我们还没有创建，后面web访问的时候如果没有会报错,所以提前创建。 Maildir: /var/mailbox/extmail.org/postmaster/Maildir/ Quota: (none) Encrypted Password: $1$phz1mRrj$3ok6BjeaoJYWDBsEPZb5C0 Cleartext Password: extmail Options: (none)[root@mail courier-authlib-0.66.2]# mkdir /var/mailbox[root@mail courier-authlib-0.66.2]# chown -R postfix.postfix /var/mailbox/
11、第十一、配置nginx访问1、nginx本身并不能解析cgi，extmail自带了解析cg坡纠课柩i的程序，但是有些地方需要值檄钕眇修改下[root@mail ~]# vim /var/www/extsuite/extmail/dispatch-initSU_UID=postfixSU_GID=postfix启动dispatch-init[root@mail ~]# /var/www/extsuite/extmail/dispatch-init startStarting extmail FCGI server...启动cmdserver，不启动会出现Connection refused[root@mail ~]# /var/www/extsuite/extman/daemon/cmdserver -v -dloaded ok2、添加nginx虚拟主机[root@mail ~]# vim /etc/nginx/conf.d/extmail.confserver { listen 8080; server_namemail.everyoo.com; index index.html index.htm index.php index.cgi; root/var/www/extsuite/extmail/html/; location /extmail/cgi/ { fastcgi_pass 127.0.0.1:8888; fastcgi_index index.cgi; fastcgi_paramSCRIPT_FILENAME /var/www/extsuite/extmail/cgi/$fastcgi_script_name; include fcgi.conf; } location/extmail/{ alias/var/www/extsuite/extmail/html/; } location /extman/cgi/ { fastcgi_pass 127.0.0.1:8888; fastcgi_index index.cgi; fastcgi_paramSCRIPT_FILENAME /var/www/extsuite/extman/cgi/$fastcgi_script_name; include fcgi.conf; } location /extman/ { alias/var/www/extsuite/extman/html/; } access_log/var/log/extmail_access.log;}生成fcgi.conf[root@mail ~]# vim /etc/nginx/fcgi.conffastcgi_paramGATEWAY_INTERFACECGI/1.1;fastcgi_paramSERVER_SOFTWARE nginx;fastcgi_paramQUERY_STRING $query_string;fastcgi_paramREQUEST_METHOD $request_method;fastcgi_paramCONTENT_TYPE $content_type;fastcgi_paramCONTENT_LENGTH $content_length;fastcgi_paramSCRIPT_NAME $fastcgi_script_name;fastcgi_paramREQUEST_URI $request_uri;fastcgi_paramDOCUMENT_ROOT $document_root;fastcgi_paramSERVER_PROTOCOL $server_protocol;fastcgi_paramREMOTE_ADDR $remote_addr;fastcgi_paramREMOTE_PORT $remote_port;fastcgi_paramSERVER_ADDR $server_addr;fastcgi_paramSERVER_PORT $server_port;fastcgi_paramSERVER_NAME $server_name;重启nginx，访问192.168.1.12:8080，出错，需要安装Unix::Syslog安装Unix::Syslog[root@mail ~]# wgethttp://www.cpan.org/authors/id/M/MH/MHARNISCH/Unix-Syslog-1.1.tar.gz[root@mail ~]# tar xf Unix-Syslog-1.1.tar.gz[root@mail ~]# cd Unix-Syslog-1.1[iyunv@localhost Unix-Syslog-1.1]# perl Makefile.PL[root@mail Unix-Syslog-1.1]# make && make install添加域名，出错编辑/var/www/extsuite/extman/libs/Ext/MgrApp/Domain.pm，把198行的can_sign改为can_signup。can_signup => $q->cgi('cansignup') ? 1 : 0,extmail正确使用extman默认管理帐号为：[email protected]密码为：extmail*123*
